THEODORE 11. FRISON 25 



developed lateral grooves; cephalic portion with punctures of moderate and 

 minute size intermixed, caudal portion somewhat polished and minutely 

 punctate. Mesoscutellum on cephalic margin with a row of rather large 

 punctures adjacent to transverse suture; disk somewhat pohshed with scat- 

 tered jjunctures, lateral margins slightly reticulate. Metanotum narrow, well 

 depressed, coarsely sculptured. Propodeum cephalad of articulation of 

 petiole of very small area, roughly punctate, limited laterally by reticulations 

 of lateral aspect. Propleura concave, punctate; humeral angles small. Meso- 

 {)leura with sulcus noticeably impressed, dorsal portion of sulcus polished and 

 impunctate; cephalo-dorsal angle weakly impressed; anterior swelling with 

 large, shallow punctures; a row of punctures adjacent to interpleural suture. 

 Metunapleura with a large, shallow, punctate ventral area, hmited dorsally 

 by a narrow, polished impunctate area; this latter limited dorsally by an area 

 of fine punctures and reticulations. Truncature concave, finely reticulate, 

 reticulations in middle portion largest; with some short whitish setae. The 

 articulation of petiole slightly cef)halad of a line drawn vertical to or dorsad 

 of metacoxal fossae. Metasternal processes slightly divergent at distal ends; 

 median coxae about the length of first flagellar segment apart, mesosternal 

 processes short and well separated. Posterior tibia and posterior metatarsus 

 with numerous stout setae and a few irregular rows of aciculae; posterior coxa 

 above rugose. Inner posterior tibial spur over twice as long as outer, two-thirds 

 as long as posterior metatarsus; posterior metatarsus somewhat over one-half as 

 long as remaining tarsal segments together; tooth of claw stouter but not longer 

 than apical ray. Wings hyaline, front wings with seven closed cells, subdiscoidal 

 and cubital veins indicated in distal portion of front wing by faint lines but 

 not chitinized. 



Petiole twice as long as distance from point of articulation to cephalic 

 margin of jjropodeum, polished, but faintly punctate and setaceous. Ab- 

 domen compressed, polished, with a few i)ale setae on dorsal portion. 



Because of the presence of distinct aciculae among the hair- 

 Uke setae, this species will run closest to E. dispersa Schletterer, 

 in Kieffer's key of 1912. E. dispersa Schletterer is said to have 

 the longer metatibial spur not one-half the length of the ])oslerior 

 metatarsus, a statement which does not hold true for E. dcUcata. 

 Also in E. delicata the posterior metatarsus is not as long as the 

 remaining tarsal segments together.
